An optical module and a manufacturing method, the polarizer

The present invention provides an optical component and a manufacturing method of the polarizer. The optical assembly includes a first layer disposed opposite the second layer, and a plurality of light absorbing film layer on the first pattern, the first and second film layers is a light transmissive layer, a second layer at a position corresponding to the light absorption pattern is provided with a hole, the hole away from the light absorbing pattern is smaller than near one end of the light absorption pattern; aperture into said light-transmitting projections. The polarizer protective film comprising; a polarizing film; the optical assembly. The display apparatus includes a display panel and the optical component. Said method comprising: a second film layer disposed on the first layer, the light absorption pattern; end remote from the first film layer a second film layer disposed on the light-transmissive projection into the aperture thereof. The optical assembly and a manufacturing method, the present invention provides a polarizing plate can be improved display luminance while expanding the viewing angle.
